To (all whom it Wan/y concern:

Be it known that I, JOHN M. SELLMAYER, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Buffing- Machines; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming a part of this specification,and to the reference-numerals marked thereon.

My present invention relates to improvernents in buffing or polishingmachines,

the present embodiment being particularly adapted for polishingsheet-metal articles, such as the tops of coffeepots, &c., and has forits object the production of a machine of this character wherein may beemployed a plurality of work-supports or heads carried upon a rotarytable or support the position of which may be adjusted both verticallyand angularly without interrupting the operation of the machine andwherein the rotary motion of the table or support is transmitted to thework-supports or heads to cause rotation thereof in a reverse directionto that of said table or support.

Another object of my said invention is to provide a buffing-wheel standparticularly adapted for use in connection with the worksupport beforementioned in which the arbor carrying the buffing-wheels is capable oflongitudinal motion and wherein the vertical position of said arbor maybe adjusted to meet the conditions of varying requirements.

Other features of novelty and advantage will be hereinafter more fullyexplained, and pointed out in the claims hereunto annexed.

In the drawings, Figure 1 represents a front elevation of a machineembodying my said invention, parts being broken away for clearness inillustration. Fig. 2 is a side elevation of the same. Fig. 3 representsa section upon the line 3 3 of Fig. 1 looking in the direction of thearrows. Fig. 4 is a plan view of the buffing-table, parts being brokenaway to more fully illustrate the parts. Fig. 5 is a detail view, partlyin section, of the elevating-gear for the buffing-wheel arbor. Fig. 6 isa detached view of the retaining-guard for the buffing-table, and Fig. 7represents a transverse section upon the line 7 7 of Fig. l with partsomitted.

In the views the same numerals of reference designate similar parts.

In the present embodiment of my invention 1 designates the mainsupporting-frame of the machine of any preferred construction, upon thelower portion of which are provided trunnion-bearings 2 3, upon whichare j0ur naled the bearings 4 5, respectively, of the secondary frame 6.Journaled in the trunnion-bearings 3 upon the main frame and mountedconcentrically with the secondary frame 6 is a main driving-shaft 7,carrying upon its outer end the belt-pulley 8, preferably flanged, asshown, and upon the inner end of this driving-shaft 7 is rigidly securedthe bevel-gear 9, the inner extremity of said shaft beyond the gear 9'being supported in a bearing 10, carried by the spacing-arm 11 adjacentthe bearings 4 5 upon the secondary frame 6. Adjacent the drivingulley 8and in alinement therewith is a be t-tightening pulley 12, journaledupon the bell-crank 13, pivoted at 14 to the main frame 1, to which thesliding lever 15 is connected at the point 16, a series of notches 17 17being provided near the operating end of said lever adapted to engagethe stationary stop 18 upon the frame 1. By adjusting the position ofthe pulley 12 through the lever 15 the slack in the belt may beeliminated to any desired degree.

At the-upper portion of the main frame and upon each side thereof areformed a pair of curved slots 19 19, each forming a sector of a circlestruck from the center of motion of the secondary frame 6. In otherwords, they lie in the path of a circle struck from the center of thetrunnion-bearings 2 3, upon which the secondary frame 6 is pivotallymounted. Passing through each of these slots 19 is an adjusting-screw20, by means of which the relative position of the main frame 1 and thesecondary frame 6 may be adjustably secured. Extending outwardly fromthe main frame 1 is a bracket or supporting-arm 21, provided upon itsupper end with a bearing 22, in which the screw 23 is revolubly mounted.This screw 23 is provided at one end with the hand-wheel 24, abuttingagainst one side of the arm 21, and with the collar 25, abutting againstthe other side thereof, to prevent longitudinal movement of said screw23. The opposite end of said screw 23 is screw-threaded and passesthrough the screwthreaded block 26, pivotally supported to permitrotation thereof about its horizontal axis by the set-screws 27 27,screw-threaded into the stationary bracket or support 28 upon the underside of the top of the frame 6,

check-nuts 29 29 being provided for retaining said screws 27 27 in theiradjusted position. By such a construction it will be understood that byoperating the screw 23 through the hand-wheel 24 the secondary frame 6may be caused to assume an angular position upon either side of thevertical, the set-screws being employed for rigidly securing said framein its adjusted position.

Upon the top of the secondary frame 6 is formed a supporting-plate 30,perforated at 31 31., and beneath which are secured the guides 32. Intothese guides 32 3.2 of the secondary frame 6 are slidingly fitted theguide-rods 33 33, secured to the under side of the supporting-plate 34.To the upper side of this support 34 is rigidly secured the annularflange 35, provided upon its inner surface with an internal gear 36. Theupper edge of this annular flange 35 is recessed, as at 37, and intothis recess is adapted to fit the annular table 38, the edge 58 thereofoverlapping to exclude the entrance of dust or other foreign matterbeneath the said table. This table 38 is revolubly fitted upon thesupporting-flange 35 and is provided with a plurality of recesses 39beneath which extend the bearings 4O 40 upon the undersidcof the table38. Resting in each recess 39 upon the upper side of the table 38 isawork-support or head 41, provided with a depending stem 42, passingthrough the extended bearing 40 and carrying at its lower end a pinion.43, meshing with the internal gear 36. Passing through each of thesebuffing-heads is an ejecting-pin 44, the head of which preferably liesflush with the upper surface of the head 41, the lower extremityextending below said gearpinion. 43. Above the upper side of thesupporting-plate 34 is located a curved camplate 46, lying in a pathdirectly beneath the path of the lower ends of the pins 44, said plate46 being pivotally secured at one end to the pivot-block 47. Beneath thefree end of this cam-plate 46 is adapted to normally rest the lever4S,pivoted at its inner end upon the pin 49, the free end 50 of thislever extendingoutside the inclosing parts, by means of which the samemaybe shifted into the position indicated by dotted lines in Fig. 4.Then this lever 48 occupies this position, the cam-plate 46 will occupythe position indicated by dotted lines in F ig. 3, and thereby causingeach pin 44 carried by the worksupport 41 to rise up into the positionas indicated by the dotted lines in Fig. 3. As each of the work-supports41 is adapted to carry an article to be polished, it is obvious that therising of said pins will lift the articles, thereby facilitating theirremoval from the work-supports without interrupting the operation of themachine. The lever 48, however, will normally occupy the positionindicated in full lines in Figs. 3 and 4.

Depending centrally from the table 38 is an extended bearing 51., inwhich is rigidly secured the upper end of the vertically-dis posed shaft52, any suitable means being adopted-such as a key and check-nut, asshown for holding the parts in fixed relation. This shaft 52 is providedupon its lower portion. with. an elongated keyway or slot 53, in whichrests the key 54, carried by the bevel-gear 55, slidingly mounted uponsaid shaft, whereby motion may be transmitted from said gear 55 to saidshaft irrespective of the longitudinal position of said gearrelativelyto said shaft. This bevel-gear 55 meshes with the bevel-gear 9upon the driving-shaft 7 and is confined from upward motion by theadjustable tln'ust-bearing plate 56, held by bolts or other suitablemeans to the stationary support 57, carried by the secondary frame 6.)ownward thrust of said gear is taken up by the thrust-bearing plate 58,mounted upon the stationary support 11 of the secondary frame 6.Therefore it will be obvious that motion of the driving shaft 7 will betransmitted through the l.)evelgears 9 and 55 to the vertical shaft 52,causing the supporting table 38, rigidly mounted upon the upper endthereof, to rotate. As this table 38, carrying the worksupports 41.,rotates, the pinions 43, carried upon said worksupports and meshing withthe stationary internal gear 36,will be caused. to rotate in z.direction opposite to the direction of rotation of saidsupprating-tab]e, a f ature the utility of which will hereinafter morefully appear. At the same time the ejecting-pins 44, passing through thework-supports, will normally remain in their lowermost position, thelever 48 beneath the caneplate 46 i'iormally resting in the positionshown in full lines in Figs. 3 and 4. However, when the polishingoperation has been completed. upon the objects upon the worksupports thelever 48 is shifted into the position indicated by dotted lines in Fig.4, causing the cam-plate 46 to assume the position indicated by dottedlines in Fig. 3, and as each pin 44 reaches the cam-plate they will beelevated successively, thereby lifting the object upon the work-support,from which position they may be readily removed by an attendant, or, ifpreferred, automatic mechanism may be employed for this purpose.

In order to prevent the articles operated upon from being displacedunder the action of the buffing-wheels, to be hereinafter described, oneor more guards 59, curved, as shown in Fig. 4, and resting directlyabove the work-supports, may be employed. This guard 59 may be held atits outer end by a clamping member 60, provided with a clamping-screw 61for retaining the same in adjusted position. This clamping member 60 isprovided with a depending stem 62, slidingly mounted in the guiding-arms63 63 of a bracket 64, carried upon the side of the supthe downwardmotion of said stem 62.

porting-table, a set-collar 65, provided with a set-screw 66, beingprovided immediately adjacent the lower arm 63 of said bracket andagainst which said collar abuts to limit Interposed between the upperside of this setcollar 65 and the lower surface of the upper arm 63 ofthe clamp 64 is a helical spring 67, the normal tendency of which is toretain said clamp in its lowermost position, and consequently hold theguard 59 down upon the bufling-heads 41. When articles of a differentheight are placed upon the work-supports 41, the height of the guard 59may be varied by adjusting the set-collar 65 upon the stem 62, theyielding pressure exerted by the spring 67 and the limit of movement ofthe clamping device being unaffected by the adjustment.

To enable work of a varying nature to be operated upon to the bestadvantage and to prevent displacement under the action of thebufling-wheels by changing the relative angle between the work and thewheels, an adjustment has been provided, as hereinbefore described,whereby the secondary frame 6, carrying the supporting-table, may bemoved to and retained .in any desired position relatively to thevertical. Vertical adjustment for the supporting-table carrying thework-supports may also be employed, and in the present embodiment thehollow screw 68 is loosely mounted over the vertical shaft 52, beingrigidly secured at its upper end by the flange 69 to the under side ofthe supportingplate 34. Meshing with the thread upon this screw 68 is aninternally-threaded wormwheel 70. This worm-wheel 70 is confined in itsupward motion by the thrust-bearing plate 71, secured to the plate 30,the down ward thrust of said worm-wheel being received upon the lowerthrust-bearing plate 72, mounted upon the support 73, carried by thesecondary frame 6, an elongated sleeve 74 being provided upon saidbearing-plate 72, forming a guide for the screw 68. Meshing with theteeth upon the worm-wheel 70 is a worm-screw 75, carried by the shaft76, mounted at its inner end in bearings 77 77 and supported at itsouter end by the bearing 78, carried by the top plate 30 of thesecondary frame, whereby relative motion between the main and secondaryframes will not destroy the mesh between said wormwheel 7 O and the worm75. A hand-wheel 79 may be provided upon the outer end of the worm-shaft7 6, by means of which the parts may be operated. Thus it will be seenthat by rotating the hand-wheel 79 in the proper direction the worm 75,meshing with the worm-wheel 70, in turn acts upon the screw 68, causingthe support carrying the work-supports to be elevated or depressedto anyheight desired within reasonable limits without interrupting theoperation of the machine. The work-supporting table will be frame 6 aremounted concentrically in the main frame 1, relative motion about thiscommon center will not affect the mesh of the gears 9 and 55. Thereforerotation of the hand-wheel 24, supported by the main frame, will causethe screw 23 to act upon the screwthreaded member 26, carried by thesecondary frame, causing said secondary frame to assume any desiredposition upon either side of the vertical without interrupting theoperation of the machine.

Located adjacent the supporting-table is the buffing-wheel stand, whichin the present embodiment of my inventioncompri ses the stationarystandards 80 80, each provided with the vertical bore 81, through whichpass the vertically-disposed pedestals 82 82, each pedestal beingprovided upon its upper end with a journal boX 83 83. Passing throughboth of these journal-boxes 83 83 is an arbor 84, carrying upon one endthereof the buffing-wheels 85 of the usual or any preferred type andprovided with a drivingpulley 86 and a loose pulley 86 of any suitablecharacter. Upon the opposite end of the arbor 84 are provided thestationary collars 87 87, between which the collar 88 is looselyinterposed. Pivotally connected to this collar 88 through thetrunnion-bearing screws 89 is the trunnion-bracket 90, secured by theset-screw 91 to the guiderod 92. This guiderod 92 is slidingly mountedin the guiding member 93, supported by the trunnion-bearing 94. At theupper portion of this guiding member 93 is a collar 95, adapted to beheld in an adjusted position upon the member 93 by the set-screw 96.Secured to this collar 95 is a pin 97, passing through the slot 98 inthe rod 99, said rod 99 being slidingly mounted in bearings 100 100 uponthe standards 80 80.

101 is an operating lever pivoted at its lower end at the point102 andprovided with an elongated slot 103, in which rests the pin 104, carriedby the stop 105 upon the sliding rod 99. By shifting thisoperating-lever 101 in either direction the arbor 84, carrying thebufling-wheels 85, is shifted longitudinally in its journal-boxes 83,causing the buffingwheels 85 to occupy any desired position upon therotary table or support, continued motion of said lever to the leftwithdrawing the buffing-wheels from the tables and throwing the beltupon the loose pulley 86 Elevating and depressing mechanism is alsoprovided for this arbor 84 and in the present embodiment comprises thepinions 106 106, both rigidly secured upon the shaft 107, suitablyjournaled in the standards 80. Meshing with said pinions 107 are therack-teeth ITO 108, formed upon each of the pedestals 82 82, wherebyrotation of said pinions 1 07 will cause the elevation or depression ofthe pedestals 82, carrying the arbor 84. Rotation of the shaft 107 iseffected through the worm-wheel 109, mounted thereon, with which theworm 110 upon the shaft 111 meshes, a hand-wheel 112 being provided,through which motion may be imparted to said worm-shaft.

I/Vhile I have shown but one buffing-stand in Fig. 1, it will of coursebe understood that two or more buHing-stands, each carrying any desirednumber of bufling-wheels, may be provided for operating eitherseparately or simultaneously upon the work carried upon the work tableor support.

In operation power is applied to the buffingwheels through the drivingpulley 86 (the lever 101 having been shifted to the po sition shown inFig. 1) and to the work table or support through the driving-pulley 8,the belt-tightening pulley 12 being ad.- justed to relieve thedriving-belt of excessive slack. From the driving-pulley 8 power will betransmitted through the drivingshaft 7 and through the bevel-gears 9 and55 to the vertical shaft 52, which in turn trans mits its motion to therotary table 38, carrying the work-supports 41, revolubly mountedtherein. By the rotation of the table 38 the pinions 43, provided uponeach of the worksupports and engaging the fixed internal gear 36, willbe rotated, the direction of rotation of the heads being in a reversedirection to the motion ofthe said table 38. The height of the rotarytable may now be adjusted through the operation of the hand. wheel 79,and the angular position of said table upon either side of the verticalmay be adjusted through operation of the hand-wheel 24, as hereinbeforefully described. Therefore it will be understood that the rotary tablecarrying the work-supports or heads maybe operated continuously, thearticles being placed upon. the work-supports or heads and removed afterbeing ejected by the pins 44, acted upon by the cam-plate 46, controlledin its action by the lever 48, without interrupting the operation of themachine. During the operation of removing and placing the forms orarticles to be polished upon the buffing-table or for setting up themachine for different classes of work the lever 101 may be swung to theleft, Fig. 1, causing the bufling-wheels to swing clear of the table,and should it be desired to discontinue the operation of the machine thesaid lever 101 will be shifted until the belt changes to the loosepulley 86", when the ro tation of the buffing-wheels will cease.

In providing a machine of this character it will be obvious to thoseskilled in the art that the possibilities in work of varyingrequirements is pratically unlimited. At the same time the constructionand arrangement of the parts combine to produce a machine of the maximumrigidity, with. a corresponding reduction in the weight of the parts andin the cost of manufacture.

In the present embodiment of my inven tion I have illustrated forconvenience of description a machine particularly adapted to be employedin buffing, burnishing, or polishing sheet-metal articles, such ascoffeepots or can-covers and the like, the work-supports 41 being soshaped that said covers will snugly fit over them to produce sufficientfrietion as to be retained in position thereon and to take up the rotarymotion of said sup ports. This retaining action will of course besupplemented by the guards 59 while the work is being operated upon bythe buffingwheels or other tools that may be em loyed. However, it willbe understood that I do not limit myself specifically to a buffing orpol ishing machine and that the work-supports may be varied in theirshape or configuration to securely hold articles of different shapes orcharacteristics and to successively bring them into position to beoperated upon by a tool of any suitable character, all of which willcome within. the province of my invention.

\Vhile I have embodied my invention in the form herein shown anddescribed, it will be understood that I do not limit myself to such formnor to the uses to which the machine may be applicable, as certain partsmay be omitted or added to and certain modifications and changes mightsuggest themselves to those skilled in the art, all of which changes andmodifications could be made without departing from the spirit of myinvention.
